  • The factory plastic barbell is approximately .020” to loose so particles as big as 500 Microns can leak passed the factory Barbell. When oil leaks pass the Barbell it goes unfiltered directly to the Cam Bearing, Lifters, Crank and Rod Bearings. Your oil filter will filter out approximately 25 Microns depending on the brand of filter. Our Aluminum Precision Billet Barbell fits with approximately .001” clearance which will let only about 20-25 Microns pass by, that is the same as the filter.
  • Our New Tapered Design and 30% smaller shaft greatly increaseoil flow!
  • We have also added a 1/4-20 threaded hole in the end of our Barbell for easy removal. Just screw a 1/4-20 bolt in and pull the barbell out. No more digging and prying to get the factory one out. Small price to pay to keep unfiltered oil out of your bearing & lifters!
